It’s not an argument. It’s a fact.
That seems definitive, good to have a rock solid source.
My local school board anyone can run. The only requirement is you are a resident of the district you represent, and you are over 18, and you are a registered voter. That’s literally it. There are no other requirements, qualifications, or criteria for running for school board.
Useful information , eligibility to run is still not the full criteria for how someone is evaluated for a position though.
Technically, i suppose it could be considered an initial screening, so you're not entirely incorrect, just incorrect that it's the only evaluation mechanism.
If it were , there'd be no need for votes, first person to apply and be eligible would automatically get the job.
